python-qrencode is not in great shape. it hasn't seen a release in 3 years and just crashes in python 3.10 because of a cython api change (Arachnid/pyqrencode#14).
python-qrcode is much better maintained and doesn't suffer from those problems. it's used successfully by the qr-backup project, see https://github.com/lincolnloop/python-qrcode
